The update also adds support for Apple’s Passbook platform. Previously, emails containing Passbook files would prompt an “Open in…” dialog with Mail and Dropbox supported, but the new version of Mailbox allows users to open Passbook files right in the Passbook app from the email as you would expect.

The update also includes a list of other changes including support for printing emails, viewing spam folder emails, spam filtering, adding stars to emails, using military time, and more.
